  1. Emerging Environmental Issues Darrell A. Fruth Brooks, Pierce, McLendon, Humphrey & Leonard LLP dfruth@brookspierce.com

  2. Trends relevant to small business • Environmental Assistance and Outreach • One-stop shop • Customer service focus • Technical assistance • Regulatory reform / simplification

  3. On the horizon • Indoor air • Vapor intrusion • Nanotechnology • Nanobiotechnology • Biochar Image from Wikipedia.org http://en.wikipedia.org/wiki/File:C60a.png

  4. What is Biochar? • Fine-grained, highly porous charcoal Feedstock Biochar Image from USDA, Agricultural Research Service, http://www.ars.usda.gov/Research/docs.htm?docid=22205#Biochar

  5. How we used to make charcoal

  6. Pyrolysis—heating biomass and limiting oxygen

  7. How is Biochar produced? Image from USDA, Agricultural Research Service, http://www.ars.usda.gov/Main/docs.htm?docid=19898

  8. What do you do with pyrolysis? Image from International Biochar Initiative, http://www.biochar-international.org/

  9. Biochar as a Soil Amendment • Improves water retention • Improves nutrient retention • Protects water quality in nearby surface waters • Reduces nutrient runoff • Reduces fertilizer use
